Determining MAWS Operation Mode
You can look at the status LED to determine the MAWS operation
mode. The LED is located on the MAWS logger board and it is visible
on the logger cover.
Establishing Terminal Connection
All MAWS software aided troubleshooting is performed using the
service terminal connection. Some of the operations can be executed
semiautomatically by the MAWS Terminal software, some require
entering the commands manually.
To connect your computer to a MAWS serial port, proceed as follows:
1. Connect the provided terminal cable (QMZ101) to the
Maintenance terminal connector on the bottom flange of the
enclosure and to an available COM port on your PC. See Figure
119 on page 173.
